In other words, in thisembodiment, the puncture portion 27 e is the second unsealing means tounseal the thin wall portion 16 (the second unsealing portion).The annular groove 27 f is that which holds an O ring 20 b sealingbetween the valve member 22 and the valve accommodating portion 12.Stated differently, by the insertion of the housing body 27 into thehousing portion 13, the O ring 20 b is compressed to seal. In addition,the annular groove 27 f is provided so that before the later describeddip tube 28 contacts the closing portion 25, and before the punctureportion 27 e contacts the thin wall portion 16, the O ring 20 b contactsthe inner surface of the housing portion 13 and is compressed.Accordingly, after sealing is formed by the O ring 20 b, the firstunsealing portion and the second unsealing portion are unsealed, thecontents are harder to leak out.

Returning to FIG. 2, the dip tube 28 is that which is connected to theconnecting portion 27 d of the housing body 27, extends to the vicinityof the lower end of the container body 11, and sucks up the concentrateC in the container body 11 toward inside the housing body 24. Moreover,the dip tube 28 is constituted so that, when the discharge device 21 isattached to the container body 11, the lower end thereof is positionedlower than the lower end of the tube portion 14. In other words, whenthe discharge device 21 (the valve member 22) is attached to thecontainer body 11, the lower end of the dip tube 28 pushes the closingportion 15 downward to remove the closing portion 15 from the tubeportion 14. Hence, in this embodiment, the dip tube 28 is the firstunsealing means to unseal the closing portion (first unsealing portion).

The valve mechanism 25 is, as shown in FIG. 3B, provided with a stem 31accommodated in the housing body 27 of the valve housing 24 to be freelymovable vertically, a piston 32 sliding on the inner periphery of thehousing body 27 in which the stem 31 is inserted, and a spring 33 whichenergizes the stem 31 upward. This valve mechanism 25 is a valvemechanism which performs aerosol discharge, and is that in which anauxiliary pump mechanism is provided, which compensates the dischargepower of the concentrate C, when the pressure of the pressurizing agentbecomes weak.

The stem 31 comprises an internal stem 36 in which a stem hole 36 a isprovided, and an external stem 37 attached above the inner stem 26,protruding upward from the container body 11 (refer to FIG. 2).

The internal stem 36 presents a cup shape facing downward as shown inFIG. 3C, and has a large diameter cup shaped portion 38 with which theupper end of the spring 33 is engagingly stopped, and a small rod likeportion 39 protruding upward from the upper surface center of the cupshaped portion 38.In the circumference of the root of the rod like portion 39 in the uppersurface of the cup shaped portion 38, an annular upper groove 38 a withwhich the lower end of a later described inside sliding portion 32 a ofthe piston 32 engages is formed. In the lower surface of the cup shapedportion 38, an annular lower groove 38 b to accept the spring 33 isformed.In the rod like portion 39, a tubular columnar portion 39 a in the sidesurface of which a stem hole 36 a communicating with the center hole isformed, a tubular oblique portion 39 b reduced in diameter upward fromthe upper end thereof, and a tubular small diameter portion 39 c formedupper than the upper end of the oblique portion 39 b are coaxiallyformed.

The external stem 37 is a portion where a later described operatingmember is attached. The external stem 37 has a tubular skirt portion 37a composed so as to surround the rod like portion 39 as shown in FIG.3D, and a tubular portion 37 b reduced in diameter extending upward fromthe skirt portion 37 a. The outer diameter of the skirt portion 37 a isof almost same diameter or somewhat smaller diameter than the cup shapedportion 38, and the inner diameter is composed so that a gap is formedacross the outer periphery of the rod like portion 39.

The tubular portion 37 b is connected to the internal stem 36 byaccepting a small tube portion 39 c of the rod like portion 39 with thelower end thereof.The upper portion of the tubular portion 37 b protrudes upward from thecontainer body 11, and to the upper portion of the tubular portion 37 b,the operating member is attached (refer to FIG. 2).

The piston 32 presents, as shown in FIG. 3E, a double tubular shape, andcomprises an inside sliding portion 32 a sliding on the outer surface ofthe internal stem 36, an outside sliding portion 32 b sliding on theinner surface of the housing body 27 and an annular connecting ring 32 cconnecting those. The connecting ring 32 c is that which connects theinside sliding portion 32 a and the vicinity of the center of theoutside sliding portion 32 b. This piston 32 partitions the inside ofthe housing body 27 into two independent spaces (a lower space S1, anupper space S2) (refer to FIG. 3B). And, the lower space S1 serves as aspace to store the concentrate C. In addition, being described later,the upper space S2 becomes in a state communicated with outside air whenthe stem 31 operates. Hence, when the inside of the container bodybecomes negative pressure by the piston whose position is restored bythe spring, outside air is introduced through the upper space S2, thegas phase communicating hole 27 c, and the gas phase introducing portion(the fractured thin wall portion 16).

The inside sliding portion 32 a is that which opens and closes the stemhole 36 a of the internal stem 36, and moves vertically between theinternal stem 36 and the external stem 37 (refer to FIG. 3B). Moreover,the lower end of the inside sliding portion 32 a receives the groove 38a of the cup shaped potion 38 of the internal stem 36 as describedabove, the piston 32 is energized upward.The outside sliding portion 32 b is that which opens and closes the gasphase communicating hole 27 c (refer to FIG. 3B). The connecting ring 32c is a portion to receive the lower end of the skirt portion 37 a of theexternal stem 37. As later described, the connecting ring 32 c receivesthe downward pressure from the external stem 37, and lowers the piston32 downward. Such piston 32 is made from elastic materials such assynthetic resin, silicon rubber, and synthetic rubber.

The spring 33 is arranged so as to be compressed between the bottomportion of the housing body 27 of the valve housing 24 and the lowergroove 38 b of the cup shaped portion 38 of the internal stem 36 of thestem 31. Thereby the stem 31 is energized upward.

The cap 26 comprises, as shown in FIG. 3B, a cap body 41, having anupper bottom 41 a, and a tubular attaching portion 42 protruding upwardfrom the upper surface center thereof. The attaching portion 42 isprovided so as to penetrate the upper bottom 41 a of the cap body 41. Inthe inside surface of the cap body 41, a female screw 41 b screwing witha male screw 11 f of the container body 11 is formed. In the innersurface of the lower portion of the attaching portion 42, a ring likecover portion 42 a protruding inward in the radial direction is formed.Moreover, in the outer periphery surface of the attaching portion 42, anengaging protrusion 42 b is formed.

Between the cap 26 and the housing 24, a presser member 43 and a sealmaterial 44 are provided. In detail, the presser member 43 has a tubularspacer portion 43 a inserted so as to make nearly close contact with theinner periphery wall of the housing body 27, an annular outer seal piece43 b extending outward in the radial direction from the upper end of thespacer portion 43 a, and an inner seal piece 43 c extending inward inthe radial direction from the upper end of the spacer portion 43 a. Thelower end of the spacer 43 a contacts with the upper end of the piston32 and positions the piston 32 in the initial state (lock position). Thelower surface of the outer seal piece 43 b contacts the upper end of thehousing body 27, and the upper surface thereof is connected with thecover portion 42 a through the seal material 44. The inner seal piece 43c suppresses the upper surface of the skirt portion 37 a of the externalstem 37, when the stem 31 is in an end position of ascending andconfines the jumping out upward of the stem 31. The seal material 44presents an approximately L shape in cross section from the uppersurface of the outer seal piece 43 b to the inner end of the inner sealpiece 43 c. This seal material 44 is pressed by the lower surfacethereof by the screwing of the cap 26, and seals between the pressermember 43 and the cap 26 and between the presser member 43 and theexternal stem 37. Hence, when the stem 31 is in a locked state (theascending end of the initial state), it contacts the upper surface ofthe skirt portion 37 a of the external stem 37 and performs sealing, andwhen the stem 31 is pushed down, it makes the upper space S2 and outsideair being capable of communicating.

The valve member constituted as described above is fixed to thecontainer body 11 so that the housing body 27 and the dip tube 28 areinserted into the housing portion 13 and the tube portion 14 of thevalve accommodating portion respectively, the female screw 41 b of thecap 26 is screwed to the male screw 11 f of the container body 11 of thecontent-accommodating container. In addition, before being completelyattached to the container body 11, the O ring 20 b of the housing body27 is compressed across the inner surface of the housing portion 13 ofthe valve accommodating portion 12, making the inside of the housingportion 13 to be in an airtight state. And, almost at the same time, orwhen the cap 26 is turned, by the lower end of the dip tube 28, theclosing portion 15 is unsealed introducing the concentrate C into insidethe dip tube 28, moreover, by the puncture portion 27 e of the valvehousing portion 24, the thin wall portion 16 is unsealed, forming thegas introducing passage.

Since, as described above, since it is possible to seal inside the valveaccommodating portion 12 (the housing portion and the tube portion 14)before the first unsealing portion is unsealed by the first unsealingmeans and the second unsealing portion is unsealed by the secondunsealing means, the concentrate C and the pressurizing agent P neverleak out to the exterior.Moreover, unsealing the thin wall portion 16 by puncture portion 27 e ofthe valve housing portion 24 to form the gas introducing passage, thepressurizing agent P is introduced into the space between the housingportion 13 and the valve housing 24, making the undiluted soliton C donot enter between the housing portion 13 and the valve housing 24. And,it is possible to induce the surely pressurized concentrate C into thedip tube 28. Further, due to the repetition of use, the pressure insidethe container body 11 becomes low, deteriorating the discharge state ofthe concentrate C, if the auxiliary pump mechanism is operated, by thedischarge of the concentrate C, the inside the container body 11 becomesin a reduced pressure state, but outside air is introduced in thecontainer body through the gas phase communication hole 27 c and the gasintroducing passage (the thin wall portion 16 and the puncture portion27 e), the concentrate C can be introduced into the inside of thehousing body 27.

Next, the operating state of the valve mechanism 25 is described. Thevalve mechanism 25 operates as shown in FIG. 4A-4C by lowering the stem31. The valve mechanism 25 is that which presents an aerosol dischargestate initially, and switches to a pump discharge state, when the stem31 is lowered more than a certain amount.

In detail, the operating member 23 is operated from the initial state ofFIG. 4A, the stem 31 is moved as large as the moving amount H1 as shownin FIG. 4B. Thereby, the internal stem 36 and the external stem 37 lowerintegrally. At this moment, the rod like portion 39 of the internal stem36 slides on the inner surface of the inside sliding portion 32 a of thepiston 32, the stem hole 36 a is released from the inside slidingportion 32 a of the piston 32. Meanwhile since the piston 32 does notoperate, the volume of the lower space S1 is maintained. Thereby,concentrate C stored in the lower space S1 from the dip tube 28 ispressurized by the pressurizing agent P, passes through the stem hole 36a, and is supplied to the operating member 23 through the internal stem36 and the external stem 37. As described above, by moving the stem 31as large as the moving amount H1, the concentrate C can be discharged asan aerosol valve.

On the other hand, the stem 31 is further moved as large as the movingamount H2, as shown in FIG. 4C, the lower end of the skirt portion 37 aof the external stem 37 contacts the connecting ring 32 c of the piston32, the lower end of the skirt portion 37 a lowers the piston 32.Thereby, the lower space S1 is compressed, the concentrate C in thelower space S1 is discharged by the applied compressing force. In otherwords, the stem 31 and the piston 32 present the auxiliary pumpmechanism.

By the lowering of the piston 32 sliding on the inner surface of thehousing body 27, the gas phase communicating hole 27 c is released fromthe outside sliding portion 32 b. Stated differently, the upper space S2upper than the piston 32 and the inside of the container body 11communicate through the gas phase communicating hole 27 c of the housingbody and the gas introducing passage formed in the housing portion 13.Thereby, the upper space S2 and the lower space S1 of the housing body27 becomes of the same pressure instantly. Thereby, the operating forceto move the piston 32 downward (the downward operating force of the stem31) decreases, the operation activity of the auxiliary pump mechanismbecomes easy. And, since the check valve 29 is provided in the liquidphase communicating hole 27 b, the concentrate C in the lower space S1never flows back to inside the container body 11, being pressurized bythe piston 32, sent to the operating member 23 from the stem hole 36 a,and is discharged outside.

When the operation of the operating member 23 is stopped, the stem 31and the piston 32 move upward by the spring force of the spring 33, atthis moment, outside air is introduced into inside the container body 11through the gas phase communicating hole 27 c and the gas introducingpassage, the concentrate C is introduced into inside the lower space S1of the housing body 27.

In addition, after the operation, by the ascending of the piston 32, thegas phase communicating hole 27 c is plugged by the outside slidingportion 32 b. However, the upper space S2 and outside air iscommunicated as described above, when the stem 31 moves, the upper spaceS2 is gradually depressurized. In other words, after the operation, thepressure of the upper space S2 becomes lower than that of the lowerspace S1, the restoring of the piston 32 to the initial state by thespring 33 is not disturbed.Meanwhile, by operating the piston 32 up to the state of FIG. 4C morethan once, the pressurizing agent in the container body 11 can bedischarged into the atmosphere through the upper space S2. After thepressurizing agent P in the container body 11 is discharged, the stem 31and the piston 32 serve as a pure pump valve to discharge theconcentrate C. Whether the pure pump valve discharge state is presentedor not can be properly set by the initial condition of the concentrate Cand the pressurizing agent P filled in the content-accommodatingcontainer 10 and the sealing force of the seal material 44.

Returning to FIG. 2, the operating member 23 comprises a spray nozzle 46attached to the stem 31 and an operating member 47 attached to the cap26. The spray nozzle 46 is an L-letter shaped tubular body and isprovided with a nozzle hole member 46 a. In the tip of the nozzle holemember 46 a, a nozzle tip 46 b is provided, constituting a mechanicalbreakup mechanism. Moreover, in the upper both sides of the spray nozzle46, a turning shaft 46 c is provided. In the lower end of the spraynozzle 46, a stem engaging portion 46 d to be connected with the stem 31is formed. Further, in the stem engaging portion 46 d, a lock groove 46e extending upward from the lower end is formed (refer to FIG. 5B, 5C).

The operating portion 47 comprises a lever supporting portion 48attached to the attaching portion 42 of the cap 26, and a lever 49mounted on the lever supporting portion 48 freely rotatably.

The lever supporting portion 48 is equipped with a tubular body 48 a anda supporting arm 48 b protruding from the side wall of the body thereof.In the lower end of the body 48 a, an annular groove 48 c to accept theattaching portion 42 of the cap 26 is formed. Further, in the innersurface of the annular groove 48 c, an engaging groove 48 d to acceptthe engaging protrusion 42 b of the attaching portion 42 is formed. Asdescribed above, by inserting the attaching portion 42 into the annulargroove 48 c, the cap 26 and the operating portion 47 are connected. Inthe upper end of an arm 48 b, a turning shaft 48 e is provided, thelever 49 is attached freely turnably. The lever 49 is that which extendscurvedly to the front end from the back end so as to cover the laterdescribed spray nozzle 46. In the tip of the lever 49, a trigger 50 forthe pulling operation with the finger is provided extending obliquelydownward in front. In the back end of the lever 49, a bearing 49 a toreceive the turning shaft of the arm 48 b is formed. Moreover, in thelower surface center of the lever 49, a bearing 49 b to receive theturning shaft 46 c of the spray nozzle 46 is formed.

Being constituted as described above, by pulling the trigger 50 of theoperation member 23, the lever 49 turns, centering around the back end,and presses the spray nozzle 46 downward through the bearing 49 b.

In this discharge device 20, an operation switching member 20 a isprovided in the valve mechanism 25 for preventing malfunction of theauxiliary pump mechanism.

The operation switching member 20 a is a tubular body, having a knobportion 51 protruding outward in the radial direction from vicinity ofthe center of the side surface, having an inside flange portion 52protruding inward in the radial direction in the upper end, and having alock portion 53 protruding upward from the center tip of the insideflange portion 52. This operation switching member 20 a is, as shown inFIG. 5, that which controls the downward moving distance of spray nozzle46 of the operating member 23. Stated differently, as shown in FIG. 5B,it is composed so that when the lock portion 53 is in the same positionas the lower end of the spray nozzle 46, the downward movement of thespray nozzle 46 is disturbed, making the stem 31 not to be moved even ifthe operating member 23 is operated. Meanwhile, as shown in FIG. 5C, byrotating the operation switching member 20 a at an angle of 90 degrees,and moving the lock portion 53 up to the position of the lock groove 46e of the spray nozzle 46, it becomes possible for the spray nozzle 46 tobe moved downward (the moving amount H1), reaching the state of theaerosol discharge. In addition, since the height of the lock groove 46 eis substantially same as the height of the lock portion 53, it iscomposed so that the lower end of the spray nozzle 46 cannot movedownward lower than the inside flange portion 52 of the operationswitching member 20 a. As described above, when the operation switchingmember 20 a is attached, the moving amount of the stem 31 (the spraynozzle 46) is regulated to be in the aerosol discharge state (the movingamount H1). Meanwhile, when operating the auxiliary pump mechanism, theoperation switching member 20 a is removed. Thereby, it is possible toprevent malfunction of the switching because of users.

The content-accommodating container 10 of FIG. 1 can be used in otherthan the discharge device 21 equipped with the valve mechanism in whichthe aerosol discharge state and the pump discharge state as shown inFIG. 2 can be switched. For example, the discharge product 60 of FIG. 6Ais that in which a discharge device 61 equipped with the aerosol valvemechanism is attached, the discharge product 70 of FIG. 6B is that inwhich a discharge device 71 equipped with the pump valve mechanism isattached. In addition, also the discharge device 61 of FIG. 6A and thedischarge device 71 of FIG. 6B, in the same way as the discharge device21 of FIG. 2, can be made into a discharge product attached to acontent-accommodating container not equipped with the valveaccommodating

The discharge device 61 of FIG. 6A comprises a valve member 62 havingand aerosol valve mechanism, and an operating member 63 attached to thevalve member. The valve member 62 is provided with a tubular valvehousing 64, an aerosol valve mechanism 65 housed inside thereof, and acap 66 which fixes the valve mechanism 65 to the inside of the valvehousing 64 and fixes the valve housing 64 to the container body 11.

The valve housing 64 is provided with a tubular housing body 67, and thedip tube 28 connected to the lower end thereof. The housing body 67 isaccommodated inside the housing portion 13 of the valve accommodatingportion 12, the dip tube 28 is accommodated inside the tube portion 14of the valve accommodating portion 12. The dip tube 28 is substantiallysame as the dip tube 28 of FIG. 1.

The housing body 67 is that which is of a cylindrical shape having abottom portion, in the upper portion thereof, a flange portion 67 aprotruding outward in the radial direction is formed, in the center ofthe bottom portion, a liquid phase communicating hole 67 b is formed.Moreover, in the inner edge of the flange portion 67 a, a step portion67 c reduced in diameter facing downward is formed. Further, in thecenter of the lower surface, a tubular connecting portion 67 d extendingdownward is formed. In the side surface of the connecting portion 67 d,an annular seal material 67 e is provided. This housing body 67 has notthe puncture portion and the side surface connecting hole.

The flange portion 67 a is arranged on the upper end of the containerbody 11 and the valve accommodating portion 12 sandwiching the annularseal material 60 a. The seal material 60 a exerts sealing action bybeing compressed in the vertical direction along with the rotation ofthe cap when the valve member is attached. Since being provided withsuch a seal structure as described above, it follows that the sealing ofthe valve accommodating portion 22 by the valve member 62 and theunsealing of the closing portion 15 are performed almost at the sametime, making it possible to prevent the pressurizing agent P fromleaking out to the exterior. The liquid phase communicating hole 67 b isa hole to introduce the concentrate C inside the container body 67.The step portion 67 c holds the stem rubber of a later described aerosolvalve mechanism 65.The connecting portion 67 d is a portion to connect the dip tube 28, andcommunicates with the liquid phase communicating hole 67 b.The seal material 67 e performs sealing between the connecting portion67 d and the tube portion 14.The aerosol valve mechanism 65 is substantially same as publicly knownaerosol valve mechanisms, and comprises a stem 65 a, a stem rubber 65 bclosing the stem hole thereof, and a spring 65 c energizing always thestem 65 a upward. The stem 65 a and the stem rubber 65 b are fixedinside the housing body 67 by the cap 66.

The cap 66 is a tubular body having an upper bottom 66 a. In the upperbottom 66 a, a center hole is formed. By the upper bottom 66 a, the stemrubber 65 b is held, and the center hole gives passage to the stem 65 a.In the inside surface of the cap 66, a female screw 66 b screwing withthe male screw 11 f of the container body 11 is formed. Further, abovethe inside surface of the cap 66 (upper than the female screw 66 b), anannular engaging protrusion 66 c which sandwiches the flange portion 67a of the housing body 67 across the upper bottom 66 a is formed.Thereby, the housing body 67 and the cap 66 can be integrally operated.

The operating member 63 has a stem engaging portion 63 a in the lowerend thereof, has a discharge portion 63 b in the side surface thereof,and has an internal passage 63 c inside thereof communicating the stemengaging portion 63 a and the discharge portion 63 b. In the dischargeportion 63 b, a nozzle tip 63 d constituting the mechanical breakupmechanism is provided. This operating member 63 is that which is of apush button type which can push down the stem by being pushed downwardfrom the upper surface. As the operating member 63, a trigger-typeoperating member such as shown in FIG. 1 may be used, the operatingmember 63 is not particularly limited as long as it can perform the pushdown operation of the stem.

In the case that a discharge device for aerosol valve only is attachedsuch as the discharge product 60, adjusting the pressuring agent by acompressed gas according to the volume of the container body, it becomespossible to maintain the discharge state of the concentrate to the last.Moreover, as the pressurizing agent, liquid gas may be used.

On the other hand, the discharge device 71 of FIG. 6B is provided with avalve member 72 having a pump valve mechanism and the operating member63 attached to the valve member 72. The valve member 72 is provided witha tubular valve housing 74, a pump valve mechanism 75 housed insidethereof, and a cap 76 which fixes the valve mechanism 75 to the insideof the valve housing 74 and fixes the valve housing 74 to the containerbody 11. The operating member 63 is that which is of a push button typesame as that shown in FIG. 6A.

The valve housing 74 is that which is same as the valve housing 24 ofFIG. 1, and is provided with the housing body 27 and the dip tube 28. Inaddition, in the lower surface of the flange portion 27 a of the housingbody 27, an annular seal material 70 a is provided. In this sealstructure also, it follows that the sealing of the valve accommodatingportion 22 by the valve member 72, the unsealing of the closed portion15, and the unsealing of the thin wall portion 16 by the punctureportion 27 e are performed almost at the same time, it is possible toprevent the concentrate C and the pressurizing agent P from leaking outto the exterior.

The pump valve mechanism 75 is a valve mechanism which pressurizesinside the valve housing 74 or inside the container body 11 by pushingdown the stem and discharges the content by the pressure thereof. Inthis embodiment, a pump mechanism is adopted, in which the contentsupplied to inside the closed space S3 (pressure chamber) providedinside the valve housing 74 is pressurized by contracting the closedspace, and is discharged. However, another pump mechanism such as a pumpmechanism in which inside the container body is directly pressurized todischarge the contents may be adopted. In addition, since the contentaccommodating container 10 of the discharge product 70 has an innerpressure (the concentrate C and the pressurizing agent P), the dischargeof the discharge product 70 is not the discharge by the pure pump valve,but depending on the content of the filled pressurizing agent P, thepressurizing agent P exerts an auxiliary role.

The valve pump mechanism 75 is provided with a tubular stem 75 a whichcommunicate the housing body 27 with outside air, being accommodatedinside the housing body 27, and being movable freely in the axialdirection of the housing body 27, a valve member 75 b receiving the stem75 a, and being movable freely in the axial direction of the housingbody, a piston 75 c provided so as to be freely movable between the stem75 a and the valve member 75 b, and to be slidable on the innerperiphery of the housing body 27, a spring 75 d provided between thelower end of the valve member 75 b and the bottom portion of the housingbody 27, and a check valve 75 e which allows the flow from inside thecontainer body 11 to inside the housing body 27 and blocks the flow frominside the housing body 27 to the container body 11. A closed space(pressure chamber) S3 being inside the housing body 27 of the valve pumpmechanism 75 is formed by the piston 75 c and the check valve 75 e.

And, by the pushing down of the stem 75 a, the valve member 75 is pusheddown to compress the closed space, the piston 75 c moves upward betweenthe stem 75 a and the valve member 75 b, the concentrate is dischargedoutside from the stem 75 a passing through between the stem 75 a and thevalve member 75 b.

In addition, in the case that a discharge device for a pump valve onlyis attached, by setting the pressure of the pressurizing agent accordingto the volume of the container body, although being the discharge devicefor pump valve only, the pressure reduction inside the container bodydue to the discharge of the concentrate can be canceled out by thepressurizing agent. Hence, even if the gas phase communicating hole 27 cand the gas introducing hole (the puncture portion 27 e and the thinwall portion 16) of FIG. 6B are not provided, it becomes possible todischarge to the last.

In the content-discharge container 80 of FIG. 7A, the closing portion(the first unsealing portion) is provided in the inside, not in thelower end of the valve accommodating portion 82. Moreover, instead ofproviding the check valve in the closing portion, a slit 81 a extendingvertically in the inner surface of the container body 81 for filling apressurizing agent is formed. In detail, it comprises a container body81 having an opening in the upper end and a valve accommodating portion82 which closes the opening, and is fixed to the container body 81. Thevalve accommodating portion 82 is provided with the tubular housingportion 13 accommodated in the container body, a tube portion 14extending downward from the housing portion 13, the lower end of whichis arranged in the vicinity of the bottom of the container body 11, anda closing portion (first unsealing portion) 83 closing the upper end ofthe tube portion 14. Moreover, a protection cover 84 is provided so asto cover the container body 81 and the valve accommodating portion 82.Moreover, the housing portion 13 and the tube portion 14 of the valveaccommodating portion 82 are substantially same as the housing portion13 and the tube portion 14 of FIG. 1. This content-accommodatingcontainer 80 also becomes a refill content accommodating product byfilling a concentrate and a pressurizing agent same as thecontent-accommodating container 10 of FIG. 1. And, by attaching thedischarge device equipped with the valve member to the refillcontent-accommodating product, it becomes a discharge product.
